The 18th century anchor with zink bar attached to prevent corrosion.

Note the difference in ballast stone distribution, the extent of seagrass surrounding the anchor and the coral growth. In 1996 the ballast stones were much further away from the anchor, its crown was practically touching the sea grass bed surrounding the site and there was no noticable coral growth on the anchor. Four years later, the ballast stones have tumbled closer to the anchor incorporating it into the patch reef, the sand halo practically begins at the crown of the anchor and a variety of corals is growing on its shank and palms.
